Ah, ok ,so the given example:

    <map:generator name="filteredFile">
     <map:generate type="file"/>
     <map:transform type="xslt" src="namespaceFilter.xsl"/>
    </map:generator>

wouldn't work as the file generator would get not src, it has to:
    <map:generator name="filteredFile">
     <map:generate type="file" src="{src}"/>
     <map:transform type="xslt" src="namespaceFilter.xsl"/>
    </map:generator>

with
   <map:generate type="filteredFile">
      <map:parameter name="src" value="some.xml"/>

+1, yes because then it would look like this:

   <map:generate type="filteredFile" src="some.xml"/>

which is much more convenient.
